UNITED STATES PATENT OFFICE.

LEMUEL HEREIN, OF TIMPSON, TEXAS;

BOLT-LOCK FOR RAILWAYS.

SPECIFICATION forming part of Letters Patent N 0. 595,775, datedDecember 21, 1897.

Application filed January 9, 1897.

To aZZ whom it may concern:

Be it known that I, LEMUEL HERRIN, a citizen of the United States,residing at Timpson, in the county of Shelby and State of Texas, haveinvented certain new and useful Improvements in Bolt-Locks for Railways;and I do declare the following to be a full, olear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention has relation to improvements in bolt-locks for thefish-plates on the meeting ends of railroad-rails; and the object is toprovide a simple, durable, and eifective device of this class.

To this end the novelty consists in the construction, combination, andarrangement of the same, as will be hereinafter more fully described,and particularly pointed out in the claim.

In the accompanying drawings the same reference numerals indicate thesame parts of the invention.

Figure 1 is a perspective view of my improved bolt-lock in position onthe rails. Fig. 2 is a similar view of the opposite side of the rail,and Fig. 3 is a cross-section through one of the bolts.

1 1 represent the contiguous ends of the rails, 2 and 3 the fish-plates,and 4 4 the bolts, which pass through the fish-plates and rail to securethe whole together.

Each of the bolts 4 is formed with the usual rectangular head 5, and thethreaded end of said bolt is formed with two parallel plane faces 6 6,by means of which the threaded end of the bolt can be grasped by awrench to turn it.

7 represents the locking-plate, formed with Serial No. 618,593. (Nomodel.)

a series of rectangular transverse recesses 8 8, which engagethe headsof the bolts to lock them in position. It will be seen that thebolt-orifices in the fish-plate 2 and the rails are plain, while thealined orifices in the fishplate 3 are threaded to receive the threadedend of the bolt, thus dispensing with the usual nuts employed on boltsof this class. This locking-plate 7 is. removably secured to thefish-plate 2 by machine-screws 9.

Although I have specifically described the construction and relativearrangement of the several elements of my invention, I do not desire tobe confined to the same, as such changes or modifications may be made asclearly fall within the scope of my invention without departing from thespirit thereof Having thus fully described my invention, what I claim asnew and useful, and desire to secure by Letters Patent of the UnitedStates, 1s

The rails 1 l and the fish-plates 2 3, in combination with the bolts 4 4formedwith the rectangular head 5, and having their threaded endsprovided with parallel plane faces 6 6, in combination with thelocking-plate 7, formed with a series of rectangular recesses 8 8 in oneedge, and the screws 9 9 adapted to removably secure said locking-plate7 to the contiguous fish-plate 2, the whole constructed and arranged,substantially as shown and described.

In testimony whereof I hereunto affix my signature in presence of twoWitnesses.

LEMUEL HEREIN.
